(a–c) Moment-0/1/2 maps of N₂H⁺(1–0) emission derived using central peak (see shaded area in A.1a). d) Moment-2 map of N₂H⁺(1–0) emission made using singlet F₁ F = 01–12. e) H₂ column density and f) excitation temperature maps. In panel (e), overlaid contour is of N₂H⁺(1–0) integrated emission at the level of 0.2 Jy beam⁻¹ km s⁻¹. The star and cross symbols are same as shown in Fig. 1. The apertures of identified cores, and a rectangular strip are overlaid in panel (a). In panel (c), rectangular boxes mark areas of hub-composing filaments (F1-F5). A contour in panels (c) and (d) displays structure traced by the JWST (see Fig. 1c).
